Let's divide 877870 by 71
We want to divide 877870 by 71.

On to step 1:
The number 71 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 71

Step 2:
When dividing 87 by 71, we get 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 71 from 87, we get 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 71

Step 3:
When dividing 167 by 71, we get 2 with a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 25 after subtracting 142 from 167.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 71

Advancing to step 4:
258 divided by 71 is 3 with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Subtract 213 from 258 to get 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 71

On to step 5:
457 divided by 71 is 6 with a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 1236.0
Deduct 426 from 457 and we're left with 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 71

On to step 6:
71 goes into 310 4 times with a remainder of 26.
The next digit of our result is 4. 
Result so far: 12364.0
Subtracting 284 from 310 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
If we divide 260 by 71, we get 3 and a remainder of 47.
The next digit of our result is 3. 
Result so far: 12364.3
Deduct 213 from 260 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 8:
If we divide 470 by 71, we get 6 and a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 12364.36
Subtracting 426 from 470 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
When dividing 440 by 71, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 12364.366
Subtracting 426 from 440 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 12364.366 and a remainder of 0.0014.
